• Background Soil organic carbon (SOC) is a composite indicator of soil quality.
• Management practices affect SOC concentration and stocks.
• There is limited information available on SOC distribution in Allophonic soils used for different crop production systems.
• We hypothesized that kiwifruit orchards may have higher soil organic carbon stocks at depth, as it has a deeper rooting system, than shallow rooted pastoral and arable production systems.

Materials and Methods
Study Sites and Management
The experiment was conducted near Tauranga (37°43S 176°06E) located in the Bay of Plenty region. The experimental sites are approximately 50 m above sea level, free draining, and have little or no compaction. The average lowest and highest monthly maximum temperature of the study site is in July (9.8°C) and February (19.3°C), respectively. The average lowest and highest precipitation of the study area is January (74 mm) and March (128 mm), respectively...
